Sarah Brown, the wife of Prime Minister Gordon Brown, has knitted 10 woollen hats to support the Big Knit campaign for the charity formed by the merger of Age Concern and Help the Aged.
The campaign asks members of the public to hand-knit hats for Innocent products, including its smoothies; the charity then receives 35p for every hat-wearing product sold. "Although I don't have much time for knitting these days, I was determined to bring my love of knitting and my passion for equality together," said Brown. The Big Knit has already raised more than £600,000.
Triple Olympic gold medallist Usain Bolt and singer Leona Lewis will support Cancer Research UK's Little Star awards. "Every one of the children nominated for the award is special," said Bolt. "They deserve to have their bravery in the face of this disease recognised. They are the true champions."
Celebrity chef Nigella Lawson and entrepreneur Duncan Bannatyne, from the TV series Dragons' Den, have donated mugs to international poverty and hunger charity Mary's Meals. TV presenter Chris Tarrant donated a mug from the 1980s gameshow 3,2,1 to the charity. The mugs will be sold in an online auction.
Former BBC news correspondent Kate Adie has written a mini-autobiography that will feature in a book to raise funds for anti-poverty charity Elizabeth Finn Care. The book, Tea and Teardrops, is a collection of stories about surviving difficult times. In her piece, Adie writes: "I'm not a Pollyanna, but I do think people are extraordinary, especially at bad times. I've seen amazing efforts by people who give help when they've got nothing, when they themselves have been struck by the effects of war or natural disaster."
Triple Paralympic gold medallist Giles Long, Olympic swimmer Mark Foster and England cricketer Owais Shah have launched a grants programme on behalf of children's charity the Variety Club and sports charity SportsAid. It will support young athletes hoping to enter the 2012 Paralympic Games.
